Rare photos show life inside North Korea's top-secret military

A North Korean woman and soldiers look at a Chinese tour boat from the banks of the Yalu River near the North Korean town of Sinuiju. REUTERS/Jason Lee Little is known about North Korea, and maybe even less is known about the country's military.

Soldiers in the military face malnourishment and hunger because of a lack of food availability and rigorous training.

Nuclear tests were conducted within the country in 2006, 2009, and 2013.

North Korea's military is now one of the largest in the world, and the exact details of conditions for soldiers stay under tight wraps. There is likely so much we don't know about the world's fourth-largest military.
